The process of attaching drywall to glue. What is drywall glue and how to use it correctly How to properly glue drywall on mounting adhesive

29.08.2019

Among the many building materials, intended for wall decoration, drywall has found the widest application. It is environmentally friendly, as it consists of natural ingredients (gypsum and cardboard). In addition, gypsum plasterboards allow you to achieve a finish that was previously beyond the power of even the most qualified specialists. The surface after installing the sheets becomes perfectly flat and ready for further work without prior elimination of elevation differences. The material is in good contact with various types finishes. But for this you need to choose the right adhesive for drywall, which will ensure maximum adhesion of the surface to the finishing components.

Properties and characteristics of glue for plasterboard

Before proceeding with the finishing of drywall using glue, the base itself must be properly cleaned of dirt and dust. In addition, two coats of primer must be applied after cleaning. This will increase the adhesive qualities of the base, increase its strength. Priming is carried out in two stages:

The first layer is applied to the entire surface, after which it is allowed to dry. The second can be applied after 24 hours.
At the second stage, the primer is performed using an undiluted mixture, and drying is also maintained for 24 hours.

The properties of the adhesive base depend on its composition and characteristics. There are four main types of glue for GKL:

mounting;
gypsum-based mastic;
specialized glue;
assembly foam.

When using mounting adhesive, it is very important to follow the technology of its preparation. It is usually indicated on the packaging. Glue for GKL of this type is applied to the base with a spatula in a circular motion. The distance between strokes should be no more than 30 and at least 15 cm. During the pasting process itself, you must carefully monitor the uniformity of the installation of the plates. Therefore, during installation, a special level is used, according to which sheets of drywall are exposed. Note that the correction of the position of the installed section is possible for the next 10 minutes.

Gypsum-based mastic

Gypsum adhesive mastic - means that the basis includes glue and lime. The glue is poured with the required amount of water and left for about 15 hours. During this period, its granules swell. After this time, 1 kg of lime is added, which must first be diluted with liquid, bringing to a thick state. To achieve this consistency, the mixture is boiled using the steam bath method. You can resort to the services of a conventional gas stove by setting a small fire. After reaching the desired consistency, gypsum is added. This type of mastic has a good adhesive feature. Setting time varies from 40 to 50 minutes.

Gypsum sawdust is prepared on the basis of sawdust and gypsum. Glue for drywall sheets of this kind has the consistency of food sour cream. To achieve such appearance necessary: mix sawdust and building gypsum in a ratio of 1 to 4. Next, add a solution of glue (1 liter of water per 25 g of dry mix). The setting time of such an ingredient is 1 hour.

Sulfate-alcohol mastic - in the manufacture, sulfate-alcohol stillage and water are used in a ratio of 1 to 4. Gypsum is added until the consistency of sour cream is reached.

Special glue

Most hardware stores sell specialized drywall adhesives. It comes in 750 ml bottles. Experts recommend using it in the ratio: 1 cylinder per 15 / sq. Such a substance should be applied around the entire perimeter, and then smeared over the remaining plane, forming stripes every 25–30 cm.

Its feature is fast setting. But the use is permissible only in cases where there are no large elevation changes.

Mounting foam

To carry out high-quality pasting of walls with drywall using mounting foam, you need:

Approximately 8-9 holes evenly over the entire area of the panel.
Around the holes obtained (at a distance of about 3–4 cm), it is necessary to drill holes whose diameter does not exceed 6 mm.
Stick pieces of foam rubber on the surface at a distance of 10 cm from each of the holes obtained.
Install a sheet of drywall on the wall surface and secure with screws. After strengthening, be sure to put on washers. This is necessary so that the panel does not “float”.
In the holes made, 6 mm are poured mounting foam.

After completing these works, the washers are removed, and the screws are sunk into the very base. Before the final strengthening and removal of washers, the sheet must be leveled with a level.

Before gluing drywall to the wall, it is necessary to assess the situation. Pasting surfaces with drywall is applicable in the following cases:

When it comes to leveling surfaces with large potholes and bumps. Using a starter type putty can fix the problem. But it is used only if there is relevant experience. In addition, this option for leveling the wall takes a lot of time. Thanks to the drywall sheet, depressions and elevations can be leveled if each sheet is fixed end-to-end.

GKL also "sits" on the glue when working with slopes after the installation of metal-plastic windows.

The technology of mounting drywall on glue

The very technology of mounting drywall on glue requires certain skills from the master. The main thing is to observe the uniform application of the material. If a thick mixture is used, then it is applied to the back side in a circular motion over the entire area. It is important to observe the uniformity of the applied circles so that the sheet lies flat on the surface to be treated. In order for the material to completely cover the entire area with front side, the plate is tapped with wooden lath. Blows should be applied carefully so as not to violate the integrity of the panel.

If glue for special-purpose plasterboards is selected, it is applied around the entire perimeter of the sheet, and then the entire back side is smeared with stripes. The distance between strokes should be approximately 25-30 cm. This will ensure the most even distribution of the adhesive over the entire area of the material.

Specialization: master in the construction of plasterboard structures, finishing works and styling floor coverings. Installation of door and window blocks, facade finishing, installation of electrics, plumbing and heating - I can give detailed advice on all types of work.

Today I will tell you how to glue drywall. This installation option is very different from the traditional frame technology, but if you understand the process and follow all the recommendations, you can get smooth walls without drilling and exposing the structure. For many, it is the frame that is the most difficult element to work on, but if you use the glue method, you can do the job much faster and easier.

Work options

Cladding the walls with drywall on glue is good because you will not oppress your neighbors with the roar of a perforator, and you will not have to check the plane of the frame for a long time. For inexperienced developers, this is the easiest option, the wall is completely closed from floor to ceiling and work is progressing quickly.

Preparatory stage

To begin with, let's deal with what is needed, especially since the list of basic materials and tools is the same for all work options, only their number changes. As for materials, we need the following:

materials	Description
Drywall	We will use a wall version with a thickness of 12 mm; ceiling sheets should not be used due to their low strength. Naturally, for rooms with high humidity you will need moisture resistant material, it has a green color. As for the height of the sheets, the most common options are 2.5 and 3 meters, you need to choose according to the height of the ceilings so that the surface is covered with one sheet
Adhesive composition	There can be many options, I myself have used at least a dozen, but I will recommend you the one that is on sale almost everywhere and is distinguished by quality and reliability. This is Knauf Perflix, it is most often sold in 30 kg bags, its price is about 300 rubles per pack. Naturally, the consumption entirely depends on the condition of the walls.
Primer	With the help of this composition, the foundation is strengthened, because for best quality installation, we need to achieve maximum adhesive adhesion. Two types of primers are used, and below I will tell you where and what kind is best to apply and how to do it correctly.

Sometimes you need to level the base with cement mortar or seal the gaps in it with mounting foam. We will not consider these work options, as we mean that you have a more or less finished surface that can be finished.

You can not do without a certain set of tools, its list is not as extensive as in the case of the frame device:

Since the adhesive composition sets within 30 minutes, it must be prepared often and in small portions. That is why it is better to have a drill with a mixer attachment on hand, otherwise you will get tired very quickly not from the main work, but from mixing the glue, and it takes quite a lot of time;

The composition is best mixed in a convenient container with low sides, its volume should be at least 10 liters;
It is very important to have a long level or a rule with a level on hand, because we will constantly check the plane of large sheets and we simply cannot do without it. This is the simplest tool, if you wish, you can also use laser devices that the pros love so much;
The adhesive can be applied with a notched or conventional spatula, trowel, small spatula. You need to choose what is most convenient for you in a given situation.

Technology No. 1 - for smooth walls

If your walls are almost perfectly even, which happens on concrete or plastered surfaces, then gluing drywall to them will be done according to the following scheme:

Since we will fasten the sheets close to the wall surface, it is necessary to lay all the wires in advance. So that they do not interfere, strobes are made on the surface right size, in which the cable is fixed, after laying the wire, you can cover it up cement mortar. In the required places, wires are brought out and holes are made for sockets and switches; special crowns of the required diameter are used for work;
The surface is cleaned of dust, after which a primer must be applied to it, if you have a conventional plastered or concrete wall, then it is best to use a strengthening composition. Sometimes there are situations when the surface is painted with oil or another and the adhesive composition will not stick to it. In this case, a special adhesive composition with a quartz filler is used; after such processing, the adhesive will hold perfectly;

Before gluing the element to the surface, it must be prepared. If necessary, a part of the sheet is cut off at the desired height, and holes for sockets and switches are cut out. The work is done with the help of simple crowns that cost a penny and can even be installed on a screwdriver; drywall material is not solid, so high power is not needed;

As noted above, the adhesive composition hardens very quickly, so you need to cook it for 1-2 sheets, especially at the beginning, when you have not yet filled your hand and have not entered the rhythm. The composition is applied to the surface with a notched trowel with a tooth size of 8-10 mm, this will ensure good adhesion and economical consumption of the mixture. Excess is removed, they can interfere with the alignment of the element;

The sheet is placed face down at the place of its installation. In general, you can immediately put it in place and apply glue there, this will even simplify the workflow. Naturally, boards must be placed under the material so that it does not get damaged on the floor and does not get dirty;
Before gluing drywall to the wall, you need to carefully lift it up and stretch the wires into the holes, if you forget about this, you will either have to tear off the sheet or cut it;
The drywall sticker is very simple: first, the sheet is gently pressed against the wall, you do not need to press hard. After that, using the rule, the places where the material should be pressed are determined, this can be done simply by tapping with my hand (I usually correct most of the flaws this way) or by applying the board and hitting it with a mallet or something else. You don't have to be too hard, better later hit again than go overboard.

In no case should you hit the level, so you will quickly disable the tool than level the walls. This is a very precise tool and using it for alignment is not a good idea.

Technology No. 2 - for moderately uneven walls

If you have level differences on the wall up to a couple of centimeters, then the previous version of the work will not work. Let's figure out how to fix drywall to glue to the wall in a different way, it has a lot in common with the above option, but there is also whole line differences. Do-it-yourself instructions for doing the work yourself consist of the following actions:

Preparation of the base, its primer and cable laying is carried out in the same way as in the case described above. The same applies to the preparation of sheets, so we will omit these points and immediately proceed to consider the workflow;
Before starting work, it is necessary to prepare the adhesive mixture, in this case its consumption will be much higher, since the application will be carried out not with a notched trowel, but in dots or heaps on the surface. With their help, you can compensate for irregularities and at the same time firmly fix the material;
The sheet is placed on the lining at the place of its gluing (work usually begins with the most protruding section of the wall), after which glue is applied to it. Points are made around the entire perimeter and are located in increments of 25 cm, in the middle of the sheet - they are placed every 40 centimeters, there should not be large voids, as this will negatively affect the reliability of fastening;

Gluing drywall begins with pulling the wires, if any, and lightly pressing the element to the surface, it should just catch on the wall. It is best to work together, so that one person constantly holds the sheet and helps to press if necessary, this is both easier and faster;
Before sticking drywall thoroughly, you need to carefully check the plane in all directions, and then determine in which places you need to press the material. After the initial alignment, another check is made, if necessary, individual sections are knocked out and so on until the result completely satisfies you. If you do not complete the work, then the next sheets will be even more difficult, remember this.

Here you need to consider another option, when drywall is glued to walls made of aerated concrete or foam concrete. In this case, we glue the GKL on the contrary, applying the composition not to the sheet, but to the wall, this provides a more reliable fixation of the material. From myself, I note that this option is less convenient and requires more accuracy when installing the sheet, it can be very easily skewed.

Technology number 3 - for walls with large irregularities

One of the common questions is whether drywall can be glued on surfaces with large differences without continuous plastering. Everything is quite feasible, but the technology will differ markedly from the options described above, the process looks like this:

First of all, you need to remove from the surface all pieces of plaster that do not hold well. That is, there should be no elements on the surface that can fall off later;
Priming also refers to the mandatory steps, the composition allows you to strengthen loose areas and reduce the absorbency of the surface, thereby improving the adhesion of the adhesive. It is necessary to apply the primer so that it gets everywhere, therefore on uneven grounds it is better to use a brush-brush, and not a roller, it distributes the solution better;

Next, you need to prepare beacons, 100 mm wide strips are cut from drywall, and we will use them to create an even base. The number of elements depends on the area to be lined, the elements are located along the perimeter of the wall, as well as vertically every 40-60 cm, based on this, calculations are made;

Next, you need to set the beacons, for this, the surface around the perimeter is first marked, so that you can see which line to set the elements on. They are also fixed with glue, the layer of which is regulated depending on the differences in the level of the walls. I recommend first sticking the elements around the perimeter and waiting for them to dry, especially since it only takes half an hour;
Then you need to glue the vertical racks, they are leveled, it is important to control the position of both each element individually and the surface in general. Check entire sections of the wall and adjust the position of the guides while the adhesive has not yet had time to harden;

When the glue on the structure hardens, you can start gluing the base material. To do this, the adhesive composition is applied in lines along the width of the guides, after which the element is gently lifted and pressed against the surface. If you have leveled the base well, then at this stage it will not be difficult to set the drywall evenly, as a result you will get a structure, as in the picture below;

Work is carried out until all surfaces are lined. Further finishing is no different from the usual version, the main thing is that the adhesive composition dries.

Sometimes, to save drywall, beacons are made not in stripes, but in the form of points, in this case it is easiest to set the topmost elements first and hang a plumb line from them to control the vertical. How to glue the sheets in such a situation? It's simple: the composition is not applied to the sheet, but to the resulting areas, so you do not have to puzzle over how to place the glue where you need it.

Conclusion

We figured out how to glue drywall to the most different grounds, you need to choose the option that best suits your conditions. If everything is done correctly, then the reliability of the walls will be no worse than in structures with a profile frame. The video in this article will help you understand some of the nuances even better, but if you suddenly have questions, then write them in the comments below the review.

There are several ways to fix the GKL to the bearing surfaces. The simplest and most inexpensive of them is to mount drywall on glue. The frameless method is so simple that a person with absolutely no experience in this field can handle it. But as in any construction process, there are subtleties and nuances in such work.

It is very easy to mount the GKL on a flat surface. But what if the walls are uneven or, as in old houses, there are significant distortions? In addition, you need the right selection of materials and some preparation before starting work.

Advantages and disadvantages of frameless mounting

As mentioned above, the main positive moments are the simplicity of the technology itself and, of course, low cost. After all, almost no complex tools or expensive materials are needed. There are no costs for the profile and various fasteners.

Using the frameless drywall installation method will suit even an inexperienced builder.

An important point will be the fact that such a finish practically does not take up the usable area of \u200b\u200bthe room, because the sheets are stacked practically on the walls.

The design itself, subject to the installation rules, will turn out to be very durable, even moderate mechanical influences are not dangerous to it.

And most importantly, the speed of finishing: you can build even walls in a room in one day.

Among the disadvantages: this method installation, it is impossible to make insulation; also, without a frame, it is impossible to create complex shapes and contours in the design of the room and in no way assemble complex multi-level structures.

But when a simple alignment of the walls in the room is planned, this is the most suitable way, which more than covers all the flaws.

What materials to use

Varieties of glue

If metal profiles for frame assembly are standardized. Then there are more adhesive mixtures. Properly selected glue will allow you to create a structure in strength that is not inferior to the frame.

Today, you can install drywall on glue using the following compositions.

A mixture of "Perlfix" from the company "Knauf".
"Polymin".
"Fugenfüller".
Gypsum mixtures "Volma".

The most commonly used "Perlfix" is a gypsum mounting adhesive, which is sold in bags of 15 and 25 kg, in dry form. It has excellent strength indicators and is not susceptible to moisture. A simple method of preparation and speed of drying brought this glue to a leading position.

"Polymin" is a polyurethane adhesive, sold in cans. Its use requires a special application gun.

Fugenfüller is a putty that dries very quickly and perfectly fastens drywall to various types of wall materials.

"Volma" is also a special gypsum mounting adhesive, which allows you to mount individual elements on different surfaces. Moisture-resistant properties allow it to be used for installation in the bathroom, kitchen and bathroom.

Instructions for use of each of the adhesives are available on the packages. The main thing is its observance, and when using gypsum mixtures, you should not cook them too much - they dry out quickly.

Drywall

GKL can have several purposes, depending on the conditions in which the walls will be mounted.

Moisture resistant. It has the ability to resist moisture.
Fire resistant. For finishing walls near hot spots.
Wall. Standard sheets used in the decoration of residential premises.
Ceiling. Thinner and lighter.

When selecting material for repair, including drywall, it is necessary to take into account the characteristics of the room.

Each of the types is selected in accordance with the characteristics of the room. The price policy of drywall types is different; you should not buy a fire-resistant or moisture-resistant sheet for finishing ordinary living rooms.

Application of frameless mounting

Installation of GKL on glue is possible in different situations, and not only on perfectly flat walls. In general, this method is used in three cases:

Finishing of smooth walls (panel and block houses).
Installation in brick buildings (minor differences within 15 - 20 millimeters).
Equalization of very large differences.

The technology for mounting drywall on glue is practically the same as any of the above cases, but with some nuances.

The main requirement for the use of this method of wall decoration is that the bearing surface must be durable, if there are emergency areas, they must be restored.

Mounting technology

Training

Surfaces must be prepared for gluing, otherwise the sheets of material will simply fall off after a while.

The entire area is cleaned using a mesh grater or sandpaper.
Poorly holding areas are upholstered and restored again.
A deep penetration primer with antiseptic additives is applied over the entire surface. Priming is carried out two or three times with an interval of 30 minutes.

Ideally, after preparation, you can run your hand along the wall, and it will not collect grains of sand and dust.

Installation of drywall on flat walls

After preparatory work start mounting. If the differences in the walls are insignificant, then the sequence is as follows:

An adhesive mixture is being prepared (for example, "Perlfix"), which is filled with water and mixed well with a mixer.
The glue is applied with a plastering spatula along all edges of the sheet in the form of dots or stripes. You can keep a distance between them of about 200 millimeters. Also on inner part apply adhesive dots in two or three rows. It is possible to apply the mounting mixture in a continuous layer, but then the consumption will increase.
A drywall sheet is applied to the wall and pressed, leveling in planes using a level. If necessary, using a mallet, you can slightly trim the edges by first placing a wooden board on the surface.
The glue dries in 30 - 40 minutes; for strength, it is recommended to add a few self-tapping screws screwed into the wall through the plasterboard.

Installation of GKL with minor differences

This method is applicable with a difference in the surface of the walls from 10 to 30 millimeters. As a rule, such irregularities are formed when brickwork walls.

After preparation, beacons need to be installed on the wall. To do this, you can use drywall scraps, cut into small squares.
The mounting mixture is prepared and applied to the wall in dots of four in a row. Prepared beacons are placed on this glue and their ratio is leveled.

For installation work of this nature, it is better to use a mixture of the Fugenfüller type, which has higher installation performance.

It is better to glue a drywall sheet in parts, since it will be difficult to level it entirely (weight is about 28 - 29 kg). A mounting compound in the form of strips is applied to the plane, and the corners are necessarily well lubricated. The sheet is pressed against the wall and equal to the level.

The main thing is that the glue should not get between the sheet and the beacons. Plasterboard plane should lie on the surface of the beacon!

The element to be glued must be tapped to make a snug fit.

Large drop installation

This procedure is used when there are significant differences on the surface of the walls (from 30 to 50 mm).

Strips of drywall are pre-cut along the length of the sheet to be mounted. They are carefully primed.
On the wall, as in the previous version, the assembly composition in the form of dots is applied in several rows.
Strips are installed on them and leveled with their level in the planes.
The wall plasterboard is cut in half and glue is applied in strips.
The sheet is pressed until it sits on the beacons.
In this case, be sure to add a few self-tapping screws at the corners and surfaces.

For large uneven walls, drywall sheets are used, which are cut into strips along the length of the sheet.

It is desirable to mount beacons on Perlfix, and the drywall itself on Fugenfüller.

If some elements are hung on the wall, bookmarks are made from wooden blocks under them.

There is nothing complicated in decorating walls with drywall for glue, the main thing is the use of one or another technology in a certain situation.

The installation method, in which a drywall sheet is attached to a vertical surface with glue, has a number of undeniable advantages. It allows you to simultaneously glue the material and level the walls, protect coatings with reverse side from impact aggressive environments and the harmful effects of microorganisms, thanks to the ease of installation technology, the budget and personal time are saved.

Installing drywall with glue saves space in the room, which, if the frame was installed, would be 5-6 cm less on the side of each wall. To make a quality installation, you will need:

decide on the choice of glue;
prepare the surface;
follow the installation instructions.

GKL sheet gluing process

To install a sheet of drywall on a wall using an adhesive method, use the products of two reputable manufacturers: Knauf (Perlfix series, Germany) or Volma (Montage series, Russia). The use of a domestic brand is preferable for the following reasons:

the cost is lower;
the consumption of the mixture for applying a layer with a thickness of 1 mm and an area of 1 m² per sickle is only 2-3 kg, compared to 5 kg of the Knauf brand;
the period of complete drying for the Volma glue is 24 hours, for the Knauf mixture it reaches 7 days;
strong adhesion to the surface due to the content of gypsum fibers in the composition;
setting time of the mixture flat surface is 1 hour, in Perlfix this threshold occurs 30 minutes after kneading, if the mixture is applied to a sickle tape, the setting period is even less (40 and 15 minutes, respectively);
easily takes the form of irregularities, after solidification does not shrink.

For do-it-yourself installation, it is preferable to use Volma glue. For a beginner, the form of packaging of the material is also convenient - 5, 15 and 30 kg. This allows you to easily calculate the material, save on costs, determine the scope of work for yourself in advance and have a certain period of time left before the mixture has time to set. The Knauf adhesive mixture is designed for professional approach. Packing form - 30 kg.

To glue a sheet of drywall to a wall with a Knauf mixture, you will need professional skills to work at a fast pace. Packing form Perlfix - 30 kg. The optimum temperature for the mass to acquire its properties is +5 degrees in conditions of normal humidity.

Packaging form for Volma glue Installation

Surface preparation

Before you start gluing a drywall sheet on Volma glue, a surface is prepared for it. To do this, using a level or a stretched cord, a series of measurements are made that reveal irregularities at the base of the walls. If the deviations do not exceed 2 cm, proceed to the following steps:

clear the walls old finish(wallpaper, paint, plaster), dust and other contaminants;
the surface is covered with two layers of primer, which increases the level of adhesion of the material from which the vertical ceilings are made (brick, concrete, wood) with glue;
if the deviations in curvature are a little more than 2 cm, a layer of plaster is applied to the wall, this will smooth out irregularities, which will then be filled with glue;
then they calculate the layout of the drywall sheets so that after installation they do not touch the floor at a distance of 10-15 mm (this space is required for the climatic adaptation of the material);

On the draft wall, you can install a crate or glue a sickle tape, which will allow the glue to adhere to the wall even more firmly.

Applying plaster over serpyanka

Glue mounting

As tools for gluing a GKL sheet with your own hands, you will need:

bucket or basin for kneading;
drill or mixer;
building level;
trowel and spatula for applying glue;
hammer with a wide board.

Installation steps:

dilute the glue in a bucket of water in the proportions indicated on the Volm package;
the calculation of the mass of the mixture is made depending on the amount of work performed and on the curvature of the walls, on average it is 10-12 liters, so that it does not have time to grab;
apply the adhesive mixture on the wall or on the drywall sheet itself, evenly distributing it over the surface with small dots in a checkerboard pattern in 40 cm increments or in stripes 15 cm wide. Such an application will allow you to adjust the location of the plasterboard relative to the vertical and horizontal plane;
it is recommended to glue the gypsum canvas from the corner of the room, for this it is gently pressed against the wall and leveled;
if the level shows that the sheet lay unevenly, by tapping with a hammer on wooden board evenly distribute the glue applied on the reverse side, reducing the resulting voids.

Distribution of glue on the surface of the GKL sheet and its correct consistency

After the installation is completed, a sickle tape is glued to the joints between the sheets of drywall for additional reinforcement of the seams. The gaps between the joints are filled with Volma glue or a special putty. Each seam is carefully processed so that subsequently moisture does not get between the joints and does not destroy the structure of the gypsum boards.

After the mass has dried, the serpentine is treated with trowel emery to remove excess glue, the primer is applied again and, after it dries, the surface of the drywall is puttied. All stages of the installation of GKL with an adhesive method are shown in the video below.

On a note

Remember, if the unevenness reaches 10 cm, it is not allowed to glue drywall on the Volm mixture, because the end result will not be of high quality: the sheet will not be able to adhere tightly to the surface, the adhesion strength will be impaired. And the consumption of glue will be unreasonably large.

Proper wall measurements before gluing GKL - the basis of high-quality installation

In such cases, it is recommended to carry out the standard installation of a metal or wooden frame. This installation method will additionally insulate plasterboard walls, hide cables and pipes. When using the adhesive method, it is not possible to carry out such work or great efforts are required to drill special grooves for electrical wiring.

In contact with

The next stage of repair after the construction of the frame of the house, overhaul premises. If earlier plaster was the main method, now GKL boards planted on drywall glue are increasingly being used. Some builders have expressed doubts about this method, considering plaster to be a more permanent way of finishing. Let's try to answer the question, is it possible to glue drywall?
Installation of drywall on glue

Mounting drywall on glue is a simpler and more versatile type of finish. In fact, they are a dry gypsum mixture consisting of dry gypsum with additives, placed in two layers of specially treated paper. The main question is which mounting method to choose:

put drywall on glue to the wall;
use mounting foam;

In order to decide which method to choose, you must first measure the differences in the unevenness of the wall. If they are within 1.5-2 cm, then GKL can be glued. If a greater spread is detected, it is recommended to align the walls using a profile. How to glue drywall, on which, they decide individually.

The process of installing drywall on glue

A more reliable, more commonly used and rational way is mounting on gypsum glue. Advantages of the technique in comparison with plaster:

ease and speed of installation;
less time-consuming process than plastering;
significantly less construction debris and dust;
gypsum, in comparison with cement, is a more environmentally friendly and “warm” material.

All these advantages make the technique popular. It remains to decide:

how to glue tiles on drywall;
what glue to choose for the gypsum boards themselves.

Types of glue for GKL sheets

Properly selected drywall adhesive largely determines the quality of the wall finish. When choosing a composition, you need to consider that almost all of them are universal, that is, they are applicable to all types of drywall surfaces.

Scheme of attaching drywall to glue They differ in setting speed, hardening time, plastic properties, but also, in the final price. It is possible to glue drywall on glue in rooms with high humidity, since all types are resistant to such an environment.

Perlfix (Knauf Perlfix).
A popular building mix with a number of advantages. Perlfix is quite elastic, almost does not shrink. Basic composition: dry gypsum with polymers, that is, the structure is ideally combined with gypsum sheets. Polymer Additives give viscosity to the composition and resistance to moisture. Contains ingredients that prevent the formation of mold, fungus. Adhesion (adhesion to the surface) is provided by the addition of fiberglass.
Glue for gypsum board It is applied both pointwise (“bloopers”) and in a continuous layer, 1.5 kg of glue is consumed per 1 m2 / 1 mm of the “Pearlfix” layer. It is easy to prepare the composition, it is enough to mix with water in the indicated proportions and knead. Bring the consistency to the degree of viscosity. Before applying "Perlfix", it is recommended to prime the walls with the compositions of the same company (Knauf), primers "Tifengrunt and Betokontakt". The dry mix is packed in paper bags of 25, 30 kg, the price starts from 300 rubles.
Glue for drywall.
Drywall adhesive Perlfix (Knauf Perlfix) In addition to Perlfix, there are analogues with similar compositions. Each manufacturer introduces its own additional components to the gypsum composition. The following compositions should be noted: Gypsolite, Ceresit, BELGIPS-Volma, Installation-gypsum, Polimin and others. Their properties are similar, but the price can differ significantly, so the price of a bag of 25 kg starts from 150 rubles.
Glue analogues Perlfix
Polyurethane adhesive in cylinders.
Universal glue, in fact, is a mounting foam that glues not only plasterboard sheets, but also tiles, polyurethane, foam plastic. The store offers a fairly wide range. Easy to apply, fast, strong adhesion to the surface. Average consumption is 1 bottle (750 ml) per 8 m2. The cost of one cylinder is from 300 rubles and more. From this point of view, dry gypsum mixes economically more profitable.

Silicone sealants.
When we glue drywall on various silicone sealants, it must be taken into account that from the point of view of economic benefits, this is not entirely advisable. We are talking about fairly large areas. Transparent, durable, water-repellent adhesive is more suitable for. The price of 310 mg is from 140 rubles per tube.

Which drywall adhesive to choose depends on the surface area, further finishing, finishing place, bathroom, kitchen or room.

Stages of gluing drywall

Along with the question of whether it is possible to glue tiles on drywall, they often ask how and how to glue drywall on a wall.

Sticking GKL sheets on glue

After the walls are primed and dry, you can proceed to the process of installing drywall.
How to glue, observing the technology?

It must be remembered that under the ceiling and above the floor it is necessary to leave a gap of up to 1 cm, the so-called expansion joints, in case of shrinkage of the house.

To do this, you can put pieces of drywall on the floor. Compositions of dry gypsum mixes stick well if they are properly diluted, and its viscous consistency holds the GKL sheet. Therefore, you need to adhere to the instructions indicated in the proportions indicated in it. , better on Knauf Perlfix, using a special 9 mm GKL sheet. It is necessary to dilute the glue in small portions, so the curing time is 20-30 minutes.

Drywall gluing technology Sequence of work:

Glue is applied to the sheet. Please note that if the irregularities are within 1 cm, then you can distribute the glue over the entire surface. Use a comb with a tooth of approximately (10 mm), apply a thin layer (8-10 mm). In case of large discrepancies, stamps (“bloopers”) are applied along the perimeter of the sheet, with a distance between them of 20 cm and in increments of 30 cm inside the perimeter;

Use of polyurethane adhesive in cylinders

Preparation for the installation process is the same as for adhesive mixtures. In order to stick the sheets, the mounting foam is applied in a thin line along the perimeter of the sheet, with a step of 30 cm inside it. Foam effective remedy, but at a cost superior to adhesive gypsum mixtures. If the sheet slides slightly, then you can fix it with dowels or self-tapping screws.
